ok, just got my Reloader B in the mail. got some balls and its not feeding constantly while its not on the gun. is it becuse of the microphone or whatever? i havent had a chance to use it on a gun. should it work once i get it on a gun?

its sound activated so unless it gets a marker sound or a loud thump it generally doesn't feed. Its a very nice loader, but if you have issues after testing it on your marker do not hesitate to call National's service department, they are amazing.
